The Milk-V Mars is a credit card-sized single-board computer that looks a lot like a Raspberry Pi. But instead of an ARM-based processor, this little PC sports a 1.5 GHz StarFive JH7110 quad-core processor based on RISC-V architecture.

It’s the latest in a line of RISC-V systems from Milk-V, and the company has been teasing the little computer on Twitter recently. While Milk-V hasn’t announced pricing or availability information yet, the company has now posted detailed specs for the Milk-V Mars on its website.

The single-board computer measures 85 x 56mm (3.3″x  2.2″) and supports 1GB to 8GB of LPDDR4 memory. It has an eMMC slot that can be used for flash storage, as well as a microSD card reader for removable storage.

Ports and connectors include:

  • 1 x HDMI
  • 1 x MIPI-DSI (2-lane)
  • 1 x MIPI-DSI (4-lane)
  • 1 x Gigabit Ethernet
  • 3 x USB 3.0 Type-A
  • 1 x USB 2.0 Type-A
  • 1 x USB-C (5V/3A power input)
  • 1 x M.2 E-Key (for WiFi & Bluetooth cards)
  • 1 x 40-pin GPIO

Milk-V says the computer can handle up to two displays if you use the HDMI port and one of the MIPI-DSI connectors at the same time. It should be able to play H.264 and H.265 videos at resolutions up to 4K/60fps and there’s support for encoding H.265 video at up to 1080p/30fps.

While the tiny computer can be used as a fanless PC, there are also pins for connecting a 5V fan. And if you don’t want to use the USB-C port for power, the GPIO headers also include power input. The system also supports Power over Ethernet.

  1. FYI: Milk-V have a Mars CM (compute module) available for preorder. It appears to be compatible with carrier boards designed for the standard RPi CM4.

    They also appear to have a future RPi3B+ form factor model coming called the Meles.

  2. [singing] Bye bye to the Raspberry pi [/singing]

    (I’d’ve be kinder had Eban Upton not been busy sowing disinformation about RISC-V recently.)

    1. I’d be interested to hear more about this?

      There’s more than a bit of a putrid whiff emanating from the State of Cambridge; vis their conduct over pre-installing Microsoft’s key in RPiOS (so that your RPi phones home to Microsoft), censoring complaints about it on their forum, reneging on their Education- and maker-based not-for-profit status, now see the comments section beneath the recent Hackaday article on the RPi’s future…very odd shenanigans!

      1. In case it’s not clear what I mean with reference to the comments section beneath that Hackaday article, yesterday there were more than 70 comments there (e.g. people suggesting their ideas for what RPiF should focus on going forward).
        Today there are just 15 (including mine pointing out this seemingly unprecedented incident).

  3. Nice! Will you keep us updated when they announce their pricing?
    Hopefully the ports are located with sufficient accuracy that it can be a drop in replacement for the RPi3B+ in people’s existing cases
